A Battle of Equals

Hacker pollutes cyberspace with dangerous cyberstatic by tampering with four satellites designed to keep everything free from cyber- static cling. But is his plan only to trash cyberspace - or does he have something even more devious up his cloak? The kids learn the answer as they use balance scales and equations to restore the satellites and save Motherboard. The Big Idea: You can use an equation - a statement that two different expressions are equal to each other - to find unknown values that make the equation true.
